Data API
This service facilitates machine-to-machine access to aviation weather information. The interface below can be used to learn more about available data, configure specific queries, and try them out. The weather database currently allows access to the previous 15 days of data.
Please keep requests limited in scope and frequency. Maximum results per query apply as well as rate limiting against frequent requests. For larger queries, consider using the cache files.
Notice: CONUS text AIRMETs will be discontinued in January 2025. G-AIRMETs replace AIRMETs, increasing forecast precision in both time and space.
Cache
Access to current observations and forecasts in one file. Use of these files is recommended instead of making excessively large or frequent custom queries. METARs, AIRMETs/SIGMETs, and PIREPS update once a minute, TAFs update every ten minutes, and stations update once per day.
